This is something we have mentioned in the article but we are only now paying more close attention to it: http://www.sierrachart.com/image.php?l=1451785554504.png This is a chart with two studies at the bottom showing that the extremes that the Sierra Chart calculated TICK for the S&P 500 stocks has are more than IQ Feed for the same S&P 500 TICK statistic symbol. What does this tell us? We are sure we are using the correct IQ Feed symbol because that is what they specify for their S&P 500 TICK symbol: http://forums.iqfeed.net/index.cfm?page=topic&topicID=3383 We cannot say with certainty, but the higher highs and lower lows, greater extremes, do indicate that Sierra Chart is delivering a much more complete data presentation. Sierra Chart does not use a sampling method but instead uses all trades of the S&P 500 stocks in the TICK calculation. This chart here indicates the number of stocks that are used in the S&P 500 TICK calculation: http://www.sierrachart.com/image.php?l=1451786374675.png It increases on December 14, 2015 but we still notice greater extremes with the SC calculated TICK for the S&P 500 before this date. You can easily validate this yourself by looking at the TICK-SP symbol. We will see why there is a jump at this date. Sierra Chart Support - Engineering Level Your definitive source for support.
